“…Observations of mood-congruent depressive biases are rather consistent for recalling autobiographical events (for further review, see Köhler et al, 2015), although the evaluation of MCM in depressed individuals for lab-learned stimuli has produced mixed findings. Yet, such investigations are surprisingly few in number, and evidence suggests that they are sensitive to the length of the encoding-recall delay (Bogie et al, 2019). That is, a more consistent MCM effect is observed in depressed versus control groups when memory is assessed at least a day later (Gotlib et al, 2004; Hamilton & Gotlib, 2008; Rinck & Becker, 2005), as opposed to shortly after encoding (e.g., Baños et al, 2001; Ellwart et al, 2003).…”

Affective experiences are commonly represented by either transient emotional reactions to discrete events or longer term, sustained mood states that are characterized by a more diffuse and global nature. While both have considerable influence in shaping memory, their interaction can produce mood-congruent memory (MCM), a psychological phenomenon where emotional memory is biased toward content affectively congruent with a past or current mood. The study of MCM has direct implications for understanding how memory biases form in daily life, as well as debilitating negative memory schemas that contribute to mood disorders such as depression. To elucidate the factors that influence the presence and strength of MCM, here we systematically review the literature for studies that assessed MCM by inducing mood in healthy participants. We observe that MCM is often reported as enhanced accuracy for previously encoded mood-congruent content or preferential recall for mood-congruent autobiographical events, but may also manifest as false memory for mood-congruent lures. We discuss the relevant conditions that shape these effects, as well as instances of mood-incongruent recall that facilitate mood repair. Further, we provide guiding methodological and theoretical considerations, emphasizing the limited neuroimaging research in this area and the need for a renewed focus on memory consolidation. Accordingly, we propose a theoretical framework for studying the neural basis of MCM based on the neurobiological underpinnings of mood and emotion. In doing so, we review evidence for associative network models of spreading activation, while also considering alternative models informed by the cognitive neuroscience literature of emotional memory bias.

“…A recent systematic review of memory bias in mood disorders suggested that depressed individuals exhibit a general memory impairment compared with control subjects (Bogie et al, 2019). The authors concluded that there was not an emotional memory bias for depressed individuals and noted that there were large differences in the time frame between the endorsement task and recall, ranging from a few minutes to a day.…”

Self-Referential Processing and Depression: A Systematic Review and Meta-Analysis

Reward devaluation theory posits that depressed individuals avoid and devalue positivity, suggesting that they may hold fewer positive self-schemas. Previous meta-analytic reviews have supported this theoretical framework regarding positivity but have not assessed for self-referential stimuli. Self-referential encoding and recall tasks assess for self-schemas and thus provide further insight into how depressed individuals process self-referential positivity. The aim of this systematic review and meta-analysis was to examine the extent to which depressed individuals differ in processing self-referential positivity and negativity and whether this processing differs when depressed individuals think of others (i.e., other-referential). Results indicate that depressed individuals recall and endorse fewer self-referential positive words than negative words and fewer self-referential positive words than other-referential positive words than nondepressed individuals. These findings support reward devaluation theory and suggest that conceptualizing self-referential processing in depression as merely based on negativity biases can overlook crucial information about how depressed individuals devalue self-referential positive information.

“…In line with this negative bias, greater instability of depressive symptomatology in patients with BD correlated with negative biases in the categorisation of emotional of self-referential emotional words (Bilderbeck et al, 2016; Godlewska & Harmer, 2021). Further emotional memory biases in BD have been observed, with patients showing enhanced memory for content that is associated with adverse emotions and for neutral content that preceded the emotional stimulus (Bogie et al, 2019; Fijtman et al, 2020). Additionally, both in BD depression and unipolar depression, patients show a worse recall for positive autobiographical memories, where these are less specific and more categorical, compared to healthy controls (Young et al, 2016).…”

“…BD is associated with impairments in cognition, and more specifically emotional cognition (Bogie et al, 2019; Fijtman et al, 2020). Patients with BD depression and unipolar depression show a more general impairment in recall and recognition processes, which seem to be related to poor encoding rather than to rapid forgetting (Bearden et al, 2006; Deckersbach et al, 2004).…”

BackgroundLamotrigine has been shown to be effective in the long-term treatment and relapse prevention of depression in bipolar disorder. However, the neuropsychological mechanisms underlying these effects are unclear. We investigated the effects of lamotrigine on a battery of emotional processing tasks, previously shown to be sensitive to antidepressant drug action in healthy volunteers.MethodsHealthy volunteers (n=36) were randomised in a double blind design to receive a single dose of placebo or 300mg lamotrigine. Mood and subjective effects were monitored throughout the study period and emotional processing was assessed using the Oxford Emotional Test Battery (ETB) 3 hours post administration.ResultsParticipants receiving lamotrigine showed increased accuracy for the recall of positive vs. negative self-descriptors, compared to those in the placebo group. There were no other signficant effects on emotional processing in the ETB, and lamotrigine did not affect ratings of mood or subjective experience.ConclusionsLamotrigine induced a positive bias in emotional memory, similar to the effects of other antidepressants as reported in previous studies. Further work is needed to assess whether similar effects are seen in the clinical treatment of patients with bipolar disorder and the extent to which this is associated with its clinical action in relapse prevention.
